Comparing automated vs manual leukocyte differential counts for quantifying the 'left shift' in the blood of neonates

摘要

OBJECTIVE: The neutrophil 'left shift' can be measured via the immature to total (I/T) neutrophil ratio or the absolute bands per I using a manual differential count. It can also be measured from an automated differential count by the immature granulocyte percentage (IG%) or the absolute IG per mu l. In neonates, it is unknown if the manual or automated differential count is superior.
